A voltage drop supplied to a logic circuit used for power gating is suppressed. In addition, power consumption of the semiconductor device is reduced. A program element including a first transistor, a second transistor, and a capacitor is provided between a logic circuit using a semiconductor element and a power supply. The program element forms a node in which the drain electrode of the first transistor, the gate electrode of the second transistor, and one electrode of the capacitor are electrically connected, and the source electrode and the capacitor of the first transistor The other electrode of the transistor can be supplied with a potential independently, and the power source and the logic circuit are electrically connected to each other through the source electrode and the drain electrode of the second transistor. Accordingly, the connection state between the power source and the logic circuit is controlled. [Selection] Figure 1 |
